The default (--verbose) output displays the AT_CHECK command line as it
is before passing it to the shell.  That's by intention, because it
might provide helpful clues as well (say, you misspelled CXXFLAGS).

To also see the expanded command line, use the --trace aka. -x flag:
  ./testsuite -v -d -x 239 242

or, if you're running from 'make', probably something like
  make maintainer-check TESTSUITEFLAGS="-v -d -x 239 242"

(-d avoids overwriting your testsuite.log file).

Cheers,
Ralf
